I can start the service, but even though the wrapper is in the firewall exclusion, it does not work unless Windows Firewall is off. Even then, the PS3 sees the service, I can watch stuff but the PMS client does not see the PS3.

If I disable the service, and enable the Windows Firewall, the PS3 sees the service, I can watch stuff, and the PMS client sees the PS3.

well i didnt read the entire thread but i had a firewall issue also make sure you turn the firewall on and you have the option that shows u when a program is blocked so you can allow it, then for the first time you run the wrapper.exe file in c:\program files(x86)\ps3 media server\win32\service so pms launches locally with a console box youll see the request then and then allow it for firewall then close the console box and go into services and run pms normally. this is what i did hope thats what u mean.
